Application filed Fehruaryfahwi. seria nmseaen Be it known that I, DANIEL STAT-Ulnar, a

citizen er the United States, residing at particailarly adapted for, applicationto corn binders and is to be disposed between the guide boards for the conveyer chalns to retard and straighten the corn stalks before they reach the binding plates so that all of the stalks will be disposed in a substantially \etiial pasition before bundling.

An other object of the invention is the pro vision of a springretarding device of the above character which. possesses points of elii iency and durability, is inexpensive to manufacture and, at, the sainetiine, is sini--t ple in construction and operation.

W 1th the above and other objects in View,

this invention consists in the novel features 01? construction and the coinbination ar-f rangeinents of parts to he hereinaftermore fully described,.pointed o'ut in the claim and shown in the accompanying drawing, in'which,

Figure 1 is a top plan view. illustrating the application of my invention; and Fig. 52 is a transverse sectional view taken on the line 92, of Fig. 1. p v

Referring more particularlyto the drawing, 1 indicates a corn binderof any general m-nstruction, having the upper guideboards 2 and the lower guide boards 3. 'jMounted upon 'the'upper guideboards are the upper sets of conveyer chains 4:, while arranged beneath the lower guide boards 3," are the lower sets of conveyor chains 5. Dis osed directly beneath the lower conveyor oiains is the chute 6, upon which the lower ends of the corn stalks ride, when'passing upwardly with the conveyerchains to the gathering prongs, not-shown.

It will he understoodthat the main object of the present invention, as stated before,.is to straighten the shorter corn stalks before they reach the bundling device, as it is a well known fact that in harvesting corn, the

shorter stalks Where the'tops thereof are not v bundling device in a linaking an 'unwenbundle rests. I g 1 a Coiled around the standard 7, isa spring with the upper (tony or chains sufficiently to retain thenrin an upright p0- s tion Wlll drop-backward and reach. the

slantingposition, thus generall main force.

y expelled from the machine by Patented SeptS, i914- a lee which-has to be t is also apparent that the thin standing row of stalks, althoughtall,will fall to the stalks,

same slanting position as the short :trcinthe fact'that they are thin; and sta i'iding far apart an'ddo notfill out thespace between thev upper conveyor chains and,

therefore, cannotbe held by the lugs on the chains, and although the'chute doesnot h'ave to be raised, for the short corn stalks, it still is disposed in an inclined position,

therefore the. frictionbetweenv the. butts of: I

L118 stalks and the chute will provide aretarding eii ectand, in vicwbf the fact that the tops of the stalks'will not be held, will; cause them to act in the same manner asthe retardi lilli which be more: fully described.hereinafter, n engage the topsof the'stalks and straighten thein betore. they reach the bundling device'.;

My improved sp i upii I ngretarder includes an 'ht standard 7, the upper end of which is, secured tothelowerfface one of the upper guide boards 2,,while the-lower end thereof'is secured by means a'bearing 7 tothe sh eld orguard S; The bearing 7 p ecured to the shield to securely retain. b. st'uidard 7 in itseflective position. .jMounted uponthe'standard at the upper end thereof, is .theretarding arm 8 which projects outwardly at right is" bolted or other angles with respect to the standard midis supported by means ofthe transverse pin 9. uponwhichthe inner end of the arm 8 10, the ends of which are fixed to the stand ard as indicated bythe numeral 11 and the intermediate portion thereof is engaged standard 7 and ar- N ED F QEEAEEM oFFIC E: f

adjusting lever 18 which is provided with a downwardly projecting blade 14 of one of the upper guide boards in any suitable manner. The blade id is yieldalily retained within any of the notches 15 by means of the spring 17, one. end oi? which is rigidly secured beneath the lever 13, as shown at 18, while the other end therecti yieldably engages beneath the rack to securely retain the lever in its effective position.

From the above it will be readily apparent that the ei'iectiv resistance of the retarding arm 8 may be readily adjusted by rotating thestandard 7 in either direc tion. From the above description taken in connection with the accompanying drawing, it will be a parent that when the corn stalks strike the retarding arm 8, they vill have a tendency to press the arm rearwardly and at the same time slide unwardl on 1 a 1 a l v the same until tney are 111 a substantially vertical position, and as the stalks press RO'SJRSC the arm the snrm 10 will be Jla-ced under tension the arm passes rearwardly around the standard 7, to allow the stalks bearing against the arm, to pass into the bundling device.

It is a w ell inovvn fact that in guiding corn wheie the stalks short and uneven, the chute upon which the-lowerends of the stalks ride is ra sed so-that' the upper ends of the stalks will with the upper eonyeycr chains. TlldS, the chute is disposed upon an inc ine, the friction of the stalks bearing against the incline will retard tne lower ends of the stalks and as there is retarding m ans for the upper endsof the stalks, they will pass rearwardly much faster than the butts of the stalks,

SQ amt when y each the/bundling d YilCQ il (1y are J generally in a slanting position and when tied together, will make an uneven bundle which has to be expelled from the machine by main force, whereas, upon the use of my attachment, the upper ends of the stalks will engage with the retarding arm 8 and are straightened before reaching the bundling device.

It will be apparent that any number of my improved retarding arms may b used upon a single harvester and disposed at intervalsupon the guide boards, so that the corn stalks which generally have a tendency to fall rearwardlyto a slanting position, will be all straightened before they reach the bundling device.

While I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying my inyenticn into practice without sacrificing any of the advantages of the invention, as defined by the scope of the appended claim.

Having thus described this invention, what is claimed is The combination with the upper and lower conveyers, of a corn harvester, of a rotatable standard disposed between said conveyers, an outwardly projecting arm inonnted thereon and adapted to rotate invdepeiidently thereof, coil spring mounted upon standard and having a portion thereof engaging the standard and another portion thereof engaging the inner end of the arm to retain the same in an operative position, a rack suspended between said conreyers, a lever mounted upon the standard whereby to rotate the same and place the .coilspring under tension, said lever engaging the racl: to retain the same in. an ad justed 2a ition, and a spring member secured at one end to the lever and having its other or free end bearing against the under side of the rack to yieldably retain thlever in an adjusted position.

, In testimony whereof I hereunto allix my signature in the presence of two witnesses.
